Question

A certain ideal gas has Cv m = a + bT, where a = 25 0
J/(mol K) and b = 0 03 J (mol K2) Let 2 mole of the gas
go from 300 K and 2 0 litre volume to 600 K and 4 0 litre
ΔSgas is
(1) 32 08 J/K (2) –12 08 J/K (3) 64 17 J/K (4) None of these

The solution is as follows:

A certain ideal gas has Cv.m = a + bT, where a = 25.0 J/(mol. K) and b = 0.03 J (mol. K2). Let 2 mole of the gas go from 300 K and 2.0 litre volume to 600 K and 4.0 litre. ΔSgas is (1) 32.08 J/K (2) –12.08 J/K (3) 64.17 J/K (4) None of these
